Based on Kepler's observations about planetary motion, what is the relationship between a planet's orbital velocity and its distance from the sun?(1 point)

Question

Responses

Distance has no effect on orbital velocity.
Distance has no effect on orbital velocity.

The greater the distance, the greater the orbital velocity.
The greater the distance, the greater the orbital velocity.

As distance is cut in half, orbital velocity decreases.
As distance is cut in half, orbital velocity decreases.

The greater the distance, the slower the orbital velocity

Answer 1

The correct response based on Kepler's observations is:

The greater the distance, the slower the orbital velocity.

Kepler's Third Law indicates that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit, which implies that planets farther from the sun orbit more slowly compared to those that are closer.
